These two radios are recent releases & still many questions that need to be answered. Whether it be how to expand the frequencies on UHF/VHF on the FT-991 to “How to program the muppets” as I was asked via email. So below is a way to program some of the memory channels.
The software is made available via WK2BYI and it seems a real good idea if you want to sit down and program memory channels into any of these radios.
Above is a link to where you can find the software and below is the PDF to have a read about the program
If I am ever able to afford one of these, I will be sure to download this software! :’)
